A Cornish tea plantation claims Brexit has "boosted" Britain's brand across the globe and led to increased interest in "all things" English.

The Tregothnan estate, which purports to produce "the most British tea in history", says the EU referendum has been very good for business.

"Tea sales just shot through the roof before the [Brexit vote]. Our theory is people were staying for that extra cup to talk with their friends about politics," said Jonathon Jones, the managing director of Trading at Tregothnan.

"Since then we've had a mini-export boom.

"I'm only guessing, but I think people around the world are talking about the UK in the way they haven't for a while."
